i in Oar Brakes and Starters, ot' which thefollowing is a speciticatiomreference being had to the accompanying drawings, in Which- Figure 1 isa plan view of a car-frame and trucks with our improvements applied.Fig. 2 isa longitudinal central section of the same 5 Fig. 3, a sectionon 'the line 3 3 ot' Fig. l; and

Figs. 4 to 14,l inclusive, detail views ot' de-` tached parts for themore perfect illustration of the construction and operation of ourimprovements.

Our invention relates to a car brake and starter constructed on the samegeneral plan as that patented to Hermon Hinckley in the United States, No. 242,533; and our improvements consist in the devices hereinafterspecied in our claims, and which cannot be well understood without iirstgoing through with a description in minute detail, which we now proceedto make.

Referring to the letters upon the drawings, A A indicate the Vcar-axles,to which are secured the chain-wheels B B, actuating the counter-shaftC, through the endless chains 1) D, and the chain-wheel b, which issecured to the counter-shaft C.

Secured to counter-shaft C bykey or otherwise, and revolving with it, isthe spider-wheel E, carrying the brake-shoes e e e e, in which arefastened the friction-blocks c e' e c. V

F indicates a sliding collar secured loosely on counter-shaft C, andhaving a short sliding motion on the shaft, and revolving withl it bymeans of a splineor other fastening. Y At one end of the collar are thelugs or earsffff, set on opposite sides. The links f' f f j" connect thesliding collar F with the brake-shoes c c c e.

G indicates another sliding collar secured loosely on the counter-,shaftC, 'having armsY extending upward andl downward. Secured to these larmsby means of the eyebolts g g g g arev the guides g g', having theirinner ends position.

H indicates au upright pivoted standard,

having levers h h proiectng in opposite directions, and the arms h' hconnected with the eyebolts g g g g by links h h. (See Fig. 12.)

I and I' indicate hangers attached to the door-timbers of the car-body.V

J indicates a hollow cylindrical friction brakewhecl,secured loosely oncounter-shaft C, having an inside annular frictional surface, and on theopposite side the hub forming a pinion, k, engaging the pinion k,whichis secured by key or otherwise to the shaft L. On the opposite end ofthe shaft L is secured the pinion 7o".

M indicates a chain-drum secured to the shaft L, which shaft issupported by the double bracket or yoke N, secured loosely to thecounter-shaft C, and held in a vertical position by having its upper endsecured to the oor-tiuxbers ot' the car-body.

To the chain-drum M are secured one end ot' each of the chains m m, theother ends being secured to the chain-wheels m m', on the hubs of whichare secured the inner ends ot' the spiral scroll-springs m" fm, fm. m.(See Fig. 10.) The outer ends of the springs are held in position by thestirrups m m, secured to the car-frame.

From the upright pivoted standard H extends the arm h, connected by arod with the cam-lever O. (See Fig. l.) c

P indicates a double-anged wheel, having on one side internal cog-gearand on the other internal V-shaped ratchet-gear. (See Figs. 5, 6, 8, and9.) This wheel is loose upon, the shaft C.

Q indicates a hub secured to counter-shaft C, by key or otherwise, andrevolviugfwith said shaft, having two arms extending in oppositedirections. Near the outer ends of each arm are hung the pawls q q,which are forced into engagement with the internal ratchet-gear ofthewheel P by the pawl-springs q q.

R indicates a friction-bar with huh secured loosely on shaft O, having aslight oscillating motion on the shaft, and carried forward with it bylugsrrcoming in contact with the springs q q. The pawls g g have each anarm extending toward the shaft O, which arms, coming in contact withlugs on the friction-bar It, force the pawls out of engagement.

On the arms of the hub Q are lugs q!" q", in which are inserted rubbercushions, against which the arms ofthe pawls strike to prevent noise. Aspiral spring is placed between the hub Q and the hub of l (see Figs. 3and S) normally to force the friction-bar out of contact with the wheelP. The Wheel P is rotated in a direction opposite to that in which theshaft Gis rotating by means of the internal gear and the geared pinionsk and le.

S indicates springs secured to the iloor-tim bers of the ear andextending downward, one on each side of the shaft O, and in contact withthe hub of the frietion-bar R. When the brake is applied the arm h ofthe pivoted standard H, by means of the connecting-rod, draws thecam-lever O forward and forces the springs S against the friction-bar R,bringing it in contact with the edge of the rim of the wheel P,which hasabaclrward motion on the shaft C, and carries with it the friction-barR, compressing one of the springs g q until stopped by the lug i comingin contact with a lug on hub Q, in which is secured spring q". Thisbackward movement ot' the friction-bar brings the proper pawl intoengagement with the internal ratchet-gear, and it is held there untilthe brake is released, when the springs m" in m" m, exerting their forcethrough the chains in m, reverse the motion ofthe wheel P, carrying withit the pawl and the hub Q and starting the car. The springs q q act asequalizing-springs to the friction-bar 1t, and bring it back to itsnormal position after the force of the springs m m m in has beenexpended, so that neither ofthe pawls will be engaged. .The friction-baris held in such position by a slot in the hub of the bar engaging acorresponding projection in a collar, i", the bar being forced along theshaft C into such position by the action of the spiral spring betweenthe hub Q and bar R. The wheel P, always revolving, when the brake isapplied, in the opposite direction to that of the shaft U and of theaxles, carries with it in a backward direction the friction-bar, so asto allow the proper pawl to be engaged. rlhe result is that in whicheverdirection the car may be moving, by simply applying the brake in theusual manner the proper pawl is set for-starting vthe car in the samedirection it was moving when stopped.

The operation is as follows: When it is desired to stop the car thedriver winds up the brake pull chain by the winch in the usualway7which, acting on the levers 7L It of the pivoted standard H, slides thecollar F forward on the shaft C and brings the brake-shoes c c c c intocontact with the inside frctional surface of the wheel J, carrying itforward in the same direction with the shaftO, and, through the gearedpinionsk and 7c', revolving the chain-drum M in an opposite directionand winding onto it the chains m m, at the same time nnwinding them fromthe chain-wheels m m and compressing the spiral scroll-sprin gs m in m mand stopping the car. To start the car the driver releases the brake,when the sprin gs m" m in" m, exerting the force stored in them by themomentum of the car, revolve the chain-drum in the opposite directionand through the ratchet start the car. The driver has but the oneoperation to perform-viz., to apply the brake and release it-which stopsand starts the car. The setting of the ratchet in the direction desiredis automatic, and always sure to be right, being controlled by thefriction-bar R. This bar may have detachable friction-blocks secured ateach end, as shown in the drawings, to be replaced when worn. Thesprings S are connected by a yoke, S', having a small roller, againstwhich the cam-lever 0 acts to prevent friction.

If desired, the mechanism shown in Fig. 3 may be hung on the axles ofthe car, either singly or in duplicate, and avoid the use ofcounter-shaft and endless chains, stopping and starting the car directfrom the axles, and the forms of many of the parts may be varied.

It will be observed that the car is stopped through the action of thesmall pinion lo of the wheel J engaging the pinion c/ which should belarger than the pinion r-of the chain-drum M. The pinions 7c 7c beinggreater in diameter than the drum would secure a leverage to compress amuch stronger spring by winding up the drum than would be possiblewithout having the drum smaller in diameter' and the pinion la ofgreater diameter than the pinion r. When the brake is released thecompressed spring acts on the chain-drum-which should belarger than thepinion [c2-at the opposite end of the drum-shaft L. This smaller pinionengages with the large internal gear-wheel, P, and by this means we geta leverage in starting, so that we thus provide a leverage for bothstopping aud starting. The momentum gained in iii'teen or twenty feet oftravel in stopping is principally expended in two or three feet oftravel in starting, thus givinga sure and strong start. The relativesize of the drum and pinions named can be varied; but it will be foundin practice that the general rule above given, respecting theirdifferences in size or diameter, is of importance.

Having thus described our improvements, what we claim, and desire tosecure by Letters Patent, is-
